p Application ined November 18, 192e. sel-n1 No. 149,011.

This invention relates to improvements in gas burning appliances and more particularly to appliances suit-abley for use in furnaces originally designed for burning solid fuel. rthe conventional type of coal-burning house-heating furnace has a circular lire pot. then gas is burned in a furnace of the lirepot type it is desirable to deflect the heat against the walls of the fire pot. Inverted cone-like battling means have been proposed for this purpose, an example of such type being shown in patent to Bigler 8845304. Heatdeflectors of the Bigler type are, however, open to the very serious objection that a den f ieetor built to fit one size tire pot cannot be used in a lire pot of substantially different size.

The present invention has for its object to provide a heat dcflector of inverted conelike type which shall be readily adaptable to fire pots of different sizes, low in first cost, easily installed, and otherwise well adapted for the purpose in view.

ln accordance with the present invention the heat deflector is made up of a numbeil of elongated bodies or members of wedgeshaped form, these bodies being arranged in overlapping relation in frusto-conical form. By varying the degree of overlap of said members along their adacent edges the deflector can be quickly and readily adapted to tit tire .pots of materially different sizes. ln order to more readily adapt the improved heat detlector to ditt'erent size fire pots, the elongated members from which the detlector is built up are preferably of the special construction shown in the drawings. While it is within the spirit of the invention to make said members from any suitable material it is preferred that they be made from a refractory material which will glow when hot and give forth radiant heat. ln addition to the above features there are other details of construction which embody other objects as will more fully appear in the detailed description of the invention.

Referring to the drawings Fig. l is a perspective view of the invention showing it as applied to a hot air furnace.

Fig. 8 is a plan view of the flanged plate on which the heat deflecting members are supported. i

rlhe present invention has been shown in connection with the fire pot 10 of a hot air furnace rlhe coal grates normally provided at the base of the lire pot have been removed and a ring gas burner let of a more or less conventional type substituted therefor. ln the drawings this burner has been shown as supported on a stand 1G resting` ou the floor of the ash pit of the furnace. Other expedients7 however, may be employed for supportii'lg the burner 'in position at the bottom of the lire pot. 'lhe usual appliance 18 for supplying the burner with gas is provided.

suitably mounted on the gas burner is a channelled ring` or plate 20 in the channel of which are disposed the individual members making up the baffling device, said members being generally indicated by numeral These members are wedge-shaped in longitudinal broad side elc.ation and are disposed within the tire pot with their lower ends' resting in the channel of the plate 20, the ineinbers being inclined ol'itwardlj,Y with their npper ends resting against the interior of the fire pot. The manner of disposing` the individual heat baffling elements 22 within the fire pot is an important part of the invention. Referring more particularly to Figs. l and 6 it will be noted that said membersare arranged in two concentric rows, the members of the outer row having their upper ends resting against the interior of the tire pot, said members being` arranged in spaced relation to each other. he members of the inner row are also arranged in spaced relation with res )ect to each other but are so positioned with respect to the members of t ie outer row that the individual members of the inner row cover the gap between adjacent members of the outer row thereby not only preventing any substantial leakage of hot gases between 7 1s a plan view of the burner shown 5.

the adjacent members but also forming with the lirepot wall a plurality of passages 24 through which the products of combustion may pass upwardly on their way to the flue of the furnace. v

The form of the individual battling members 22 is an important feature of the in vention. Vlhe individual members in trz'msverse cross-section are generally rhombic in form as shown in Fig. l. rllhe thickness of the rhomb through points a and 7) is substantially the same throughout the length of the body. Due to the fact that the body is made wedgeshaped as viewed in longitudinal broad-side elevation the opposite ends e and l of the rhombic fieure shown in Fig l become more blunt toward the small end of the body. ln other words, if the member 22 is viewed in longitudinal edge elevation as in Fig. 3 the edge assumes the shape of an inver 'ed wedge which for convenience of cescription is designated by reference numeral 26. The small end of the body is preferably bevelled as at 2S in order to facilitate the seating of the body in the channel of the annular supporting plate 20. The upper end of said member is preferably bevelled as at 30 in order to facilitate the positioning of the members within the fire pot.

There are numerous advantages in malt-- ing the individual heating members of the form indicated. By making them generally rhombic in transverse cross-section (rhombic when the adjacent sides are extended to meet) it will be readily appreciated that Athe sides of the members opposed to the lire pot conform in a general way with the contour or curvature of the lire pot. The principal =.id\'anta fe, however, is that better joints along the overlapped edges are produced.

By leanin the individual members making up the battling device outwardly against the fire pot, the flames issuing from the gas burner tend to scour or scrub the adjacent surfaces of said members, and they consequently become very hot. Said members are preferably of a refractory material which will glow when hot and consequently will radiate heat to the adjacent fire pot walls. The sides or the faces of said members which are exposed to the flames are preferably provided with a plurality of knobs or projections 32 in order to 'ellfect a more thorough scouring or scrubbing action of the hot gases on the material. Furthermore, these projections quickly become glowing hot and thus begin to radiate heat before the main body of the battling element has become su'liicientl y hot to glow. l

ne hot pass upwardly between the lire pot wall and the adjacent battling elements through the passages 24.

The individual ba'llliu'g elements constructed in accordance with my invention are easily manufactured and are strong and rngged. They also lend themselves to a ready disposal .vithin the lire pot. It will be readily appreciated that a heat baffling device constructed and arranged according to my invention 'is lvery readily adaptable to various sized .lire pots. i
